Chakma. A.’ Enerm Convers. Mm. Jun.-Sev. 1995. 36. (6). 427-430. An me& efficienCy proprietary &x&J solveni for the se ‘ation of CO, from power plant flue gas streams haa been developed. Tr e solvent wmbinesihe higher reaction rate of a more reactive solvent and the lower heat of reaction of a less reactive solvent end achieves mass transfer rates similar to more reactive monoethanolamine (MBA) solvent via a catalytic mechanism. The regeneration energy required is 30% less than conventional MEA. Solvent losses and corrosion rates are 10 and 5 times lower than MEA, respectively.

Discumes the major outcome of ‘tie Earth Summit ii992 which was affirmation of the organic link between sustainability and economic development. One of the-ptocols signed by world leaders at the convention was the Framework Convention on Climatic Change, aimed at reducing greenhouse gas emissions, particularly carbon dioxide, into the atmosphere. The Convention called on developed countries, which generate most of the greenhouse gas emissions, to take the lead in combating climate change and its adverse effects.

Regrettably, this development process is inevuably accompanied by environmental llution.

(In Chinese) Based on the ublic health risk evaluation method, the health risks due to the gaseous c I uents containing chemicals and radionuclides from a ty ical coal-fued power plant are evaluated. The results indicate that the he Byth risks from chemical effluents are much more severe than that of radionuclides.

The~NO, were ad&bed into a char bed and~then reduced by the microwaves to nitrogen and carbon oxides. High removal rates of NO, near 98%, were observed in laboratory tests. A series of experiments were conducted to fiid the effect that microwave-induced regeneration of Nt+ saturated char had on the NO= adsorption capacity of char and the resultmg adso tion rate. During the g-cycle adso tion and reduction experiments, xc adsorption capacity of char increas3 from 10 to 30 g NO, per 100 g char.

Although there are sufficient technical means for preventing waste water from becoming seriously polluted, in practice the unplementation of prcventive measures lags far behind the possibilities. Many reasons can be suggested for this, such as ignorance and economic uncertainties, but very little research, if any, has been carried out into the way in which entrepreneurs’ behavtour can be influenced in ractical situations. In a pilot study in The Netherlands, the Institute for lnf and Water Management and Waste Water Treatment (RIZA) investigated the attitudes within garage firms, the environmental aspects of management in garages regarding the working procedures within the firms, and in what way they are influenced by the social environment.

Sustainable deployment of bioenergy production systems rquires that we achieve the ability to predict the impact of intensive harvesting on forest site productivity. During the period 1992-94, collaborators in International Energy Agency Biomass Agreement (IEA/BA) Task Ix Activity ‘Environmental consequences of intensive harvesting have refined protocols for conducting field and laboratory research designed to reduce uncertainty associated with predictive models; have published comprehensive reviews of the state of our knowledge related to long-term productivity in intensively managed forests; have sought to improve our understanding of recent research advances on theoretical and empirical levels in the areas of carbon cycling, sustainable forest managemnt,and mana ing site fertility; and direct the mformation to developing acceptable and ek lctent bioenergy production systems.

The characteristic behaviour induced by the CO, hydrate is reported, which are CC+ injection from a nozzle, formation of CO, pool and growth and propagauon of hydrate-clathrate film induced by the nucleation. A laser dragnostic technique is demonstrated in the measurement of non-uniform two dimensional pH distribution, which is considered to be an effective tool to elucidate the mechanism of the dynamics of liquid Co,.

90lO2050 Envlronmental lmpllcstlons 1996, 53, (1). 89-117. Hill, R. and Mortimer, N. Applied Energy, Combined heat and power systems often have financial advantages compared with the central generation of electricity and its transmission and distribution to the end user, plus some local source of heat rovision. Because the heat losses in central electricity generation and distn*Iiution are rejected to the atmosphere, it is always more efficient to use rimary fuels in CHP mode than in separate electricity and heat pr OBuction. This increased efficiency in utilisation of primary resources has significant consequences in the reduction of gaseous emissions per unit of us&l energy delivered to the end user. A further reduction in total UK emissions is possible if gas-fired CHP is installed as a replacement for coal-fired central electricity generatin stations. This study of the environmental benefits of CHP has considere % only gas-fired CHP technologies.
